Part Number: UCC28713 Hello there,
Me and my team have designed a flyback supply based on the UCC2871x Controller. The supply is supposed to deliver 36V (main/controlled winding), and 12V from an additional winding. The output power is approximately…
The WEBENCH design tool is designed around the typical application parameters for an AC input. However, the devices are guaranteed to work as long as the input is higher than the UVLO turn on point such as 23V for both the UCC28713 and UCC28700.
The…
Part Number: UCC28713 Hello and thank you for your support,
In reference design PMP10351 there is Transformer T1 which is not specified and I can not find that part number. There is part number G144071LF from GCI Technologies but something is wrong…
Hi Yue,
Thanks for the additional information. I would suggest taking a look at one of the UCC2871x flyback controllers. The DC input UVLO can be set by the VS resistors in this controller family

Hi Navi,
Sorry for the delayed response. Please see my answers to your questions below:
1. While not designed for 75VAC to 275VAC, this design will still operate across that range.
2. The output voltage can be adjusted by changing the value of R9…
Hello TI Team,
I would like to use the PMP4390 reference design ( UCC28713 controller).
Could you provide the Altium readable design files?
Thank you and I look forward to your response.
